Battery
use is only recommended for short durations of time. Due to high
wattage, batteries will last 1-2 hours when used consecutively. Battery
operation is not meant for long time use.

For
extended use, we recommend using the included USB cable. This cable
cord can be plugged into tablets, laptops, computers, or used in tandem
with your cell phone USB power block into an outlet. With the USB power
block, the neon lamps can be plugged into any standard outlet.

Although
it can give you the battery options for short term use, we would
recommend customers are aware this is mainly to be plugged in because batteries wont last long.
